Waterfall Model : The waterfall model is a Sequential Software Development process in which progress is seen as flowing steadily downwards through the phases of Conception, Initiation, Analysis, Design, Construction, Testing and
Maintenance

Prototype Model: In Prototype Model, a Prototype is built to understand the requirements. This Prototype is developed based on the currently known requirements. Development of the Prototype obviously undergoes design, Coding and testing. But each of these phases is not done very formally or thoroughly. By using this prototype, the client can get an "actual feel" of the system, since the interactions with prototype can enable the client to better understand the requirements of the desired system.

The Spiral Model is a software development process combining which elements of both design and prototyping-in-stages, in an effort to combine advantages of top-down and bottom-up concepts. Also known as the Spiral lifecycle Model. This Model of development combines the features of the prototyping Modal and the Water fall Modal. The Spiral Modal is intended for large, expensive and complicated projects.

In water fall model, the customer requirements are very clear, so verification is enough, validation is not req. The water fall model and V-model are suitable for small type of projects.

In the V-model the customer req. are not clear so, both verification and validation is needed.
